calling a form from sum main

[kaisersoze]

developing windows base app in vb.net

I have a sub main in a module and sub main is activated first to do some initial settings, then it should load frmMainMenu. No run time errors but, during running the app. the form is loaded only for few seconds and the app. closes by itself.

 

Here is the code:

vdbAccess = New dbAccess

If vdbAccess.TestDatabaseConnection(gblConStr) = False Then

MsgBox("error in database connection")

End

End If

 

Dim objMainMenu As New MainMenu

objMainMenu.Show()

objMainMenu.Activate()

Before the end of Sub Main you need to do something like

application.Run(objMainMenu)

Just to give you the right code...

 

vdbAccess = New dbAccess
If vdbAccess.TestDatabaseConnection(gblConStr) = False Then
MsgBox("error in database connection")
End
End If

Dim objMainMenu As New MainMenu
Application.Run(objMainMenu)

'The code placed here will only run when you close the application...

 

Alex :p

Why it's happening ?

 

Because when you "Show" your main menu... it'll process the other line afting showing it. And when a program reach the end of the "Main"... it close by itself.

 

Application.Run(objMainMenu) make your application go in a listening loop (for events, etc. ) so your application don't close immediatly.
